\noindent This is a research of the different standardization interests within the Symbian consortium and an analysis of the effects of these. We depict the reasons behind the extinction of Symbian and outline how they can be explained from a standardization point of view.

By the use of Kvale's theory of qualitative data gathering and a thorough theoretical analysis we conclude that there were indeed different interests in Symbian, and by analyzing them from a standardization perspective it is revealed that imbalance in the ecosystem leadership has had a negative impact on Symbian's ability to innovate and compete on the mobile platform market. Especially one partner indirectly took control of the interfacing standards in Symbian, which resulted in knowledge depreciation and lock-in situations that complicated Symbian's ability to pursuit the changing demands of the customers.
